Application led July 12,

To all whom it may concern:

Be it known that l, EDWARD R. NICHOLS, a citizen of the United States, residing at Bridgeport, in the county of Faireld and State of Connecticut, have invented certain new and useful Improvements in a Knife Sharpener, of which the following is a specification.

This invention relates to sharpeners for knife blades and the like, and the object thereof is to providea simple and ineXpen* sive device of this character capable of readily sharpening knifes and adapted to hold the blades in proper position in order that an inexperienced person may accurately sharpen a knife thereon.

Withthese and other objects in view, the invention consists in certain novel features of construction as hereinafter shown, de. scribed and claimed.

In the accompanying drawings:

Figure 1 represents a front elevation of a knife sharpener constructed in accordance with this invention, with a knife blade shown in operative position relative thereto.

Fig. 2 is a vertical section taken on the line 2 2 of Fig. l.

Fig. 3 is a transverse section taken on the line 3 3 of Fig. 2.

Fig. 4 is a front view with the sharpening tool removed.

Fig. 5 is arear elevation with the tool removed.

Fig. 6 is a detail vertical section taken on the line 64-6 of Fig. 4.

Fig. 7 is a transverse section taken on the line 7-7 of Fig. 4.; and

Fig. 8 isa similar view taken on line 8-8 of Fig. 4. f f

vIn the embodiment illustrated the sharpener constituting this invention comprises combined supporting base and attaching means in the form of oppositely extending apertured feet l and 2, designed to be mounted on a suitable support, such as a table top, bench, or against the wall, and held engaged therewith by screws passing through the apertures in said feet.

A standard 3 rises from the base, and is bifurcated at its upper end, with the furcations 4 and 5 thereof flared, as is shown clearly in Fig. l, and the standard 8 has its outer face provided with a substantially V- shaped vertically disposed groove or seat 7 extending from the base of said furcations to the bottom of the standard and in which 1921. serial No; y saines.

is adjustably .secured a sharpening tool. This .tool 6 is lengthwise adjustable on they shown triangular in cross section.

`seat 7 and corresponds in'shape thereto, as

laterally projecting and outwardly bowed tool guide 8 is formed integral with the standard 3, intermediate its ends, and between said guide 8 and the walls of seat 7 the tool 6 is held in position by a securing wedge 9, as shown clearly in Figs. 2 and 3.

The sharpening tool 6 is made equilateral triangular in cross section so that the faces thereof against which the knife blade B is sharpened, may be changed when one is worn or when itis desired to change the knife engaging surface of the tool for any purpose.

In the use of the sharpener, the attachingr feet l and 2 are connected with a suitable support to hold the Idevice rigid, and then the sharpening tool 6, which is Apreferably y constructed of hard steel, although it may be made of any suitable material, is inserted in the seat 7 and secured in the desired position therein by means of the wedge 9. The tool is then ready for use, and a blade B to be sharpened is drawn through the space r between one face of the tool 6 and one of the furcations 4 or 5, asis shown clearly in Fig.y l, so that opposite sides of the blade are sharpened correspondingly.

The preferred embodiment of the invention is disclosed in the drawings Land set forth in the specification, but it will be un-y derstood that any modifications within the scope of the claimed invention may b e made in the construction without departing from the principle of the invention or sacrificing any of its advantages. What l claim is:

1. A knife sharpener comprising a standment interposed between the guideand the sharpening element, and oppositely extending apertured feet integral with the-lower end of the standard.`

2. A knife sbepener Compsng e siendeld having its upoef pofton forme@l with a, V-shuped opening and having its outer face provided Wtl'l a vertical 1l-shaped seat depending from the bottom of the opening and extending to the onfer end of be standard, a laterally projecting and outwardly bowed tool guide negrel with the outer face of the standard and opposing said seat, e sherpenng element of equlaeml Contour mounted on 1the lseec and projeetlng lnto seid opening and having be projected portion thereof opened by be Wells of the opening, said element being lengthwise adjustable on its seat, av Wedge shaped seculng element interposed between the guide and the sharpening element, and oppositely extending apertured feet integral .'fzf'ith' the lower end o the standard.
